DRAFT-RIGGING.

SPEGIFICATIQN forming part of Letters Patent No. 673,419, dated May 7, 1901.

T0 @ZZ whom it muy concern:

, Be it known that I, JACOB J. BYERs, of Cameron, in the county of Clinton and State of'Missouri, have invented` a new and useful Improvement in Draft-Riggings, of which the tion, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side elevation showing the upper part of the figure in central longitudinal section. Fig. 2 is a sectional plan view on the lines II II and IIa IIa of Fig. l. Fig. 3 is an end view, the left-hand portion of which is in vertical section on the line III III and the remainder in vertical section on the line IIIa IIIa. Fig. 4L is an elevation of the inner side of the follower. Fig. 5 is a sideview of the follower. Fig. 6 is a side elevation of a modified construction. Fig. 7 is a bottom plan View of Fig. 6, partly in section and showing the bottom plate removed. Fig. 8 is an end elevation showing the draw-bar shank Fig. 9 is an end view of the stop. Fig. 10 is a top plan view of a modified construction, showing the draftarms integral with the part of the rigging which contains Fig. 1l is a side elevation of Fig. 10. Fig. 12 is a cross-section on the line XII XII of Fig. 10.

In Figs. l, 2, and 3, 2 represents the shank of a draw-bar, and 3 represents a pocket which contains the springs of the draft-rigging and is set between draft-timbers, (not shown,) to which it is affixed by bolts 4 4. The pocket may be cast in a single piece and is provided with horizontal lugs 5 5, which extend across the pocket, above and below, and constitute abutments for the followers 6 6', which are set in the pocket. The pocket and lugs are suitablybraced by metal ribs or anges, as shown. 7 7 are the springs, placed, preferably, one above the other between the followers, and to hold them in place, as well as to limit the approach of the followers, I may provide the latter with lprojecting stops 8, which extend from such followers between the springs. The draw-bar shank 2 is connected `with the rear follower 6 by a yoke 2', which is fixed to the draw-bar by riveting or otherwise and extends within the pocket, be-

is made possible by taking o a cap-plate 9, which closes the opening at the bottom of the pocketrand is secured by bolts 9, and the l follower-plates can then be pried ont by means tween the lugs and around the rear follower, as shown. The pocket is open at the bottom, so that the follower-plates and springs may :be removed freely from within the yoke in a' 55 vertical direction without the necessity of disfollowing is a full, clear, and exact descripv` engaging the yoke from the draw-bar, since the follower-plates are not connected with the draw-bar otherwise than by being placed be-` tween the sides of the yoke. This removal of a tool applied to toothed recesses l0, formed in the edges of the follower-plates. To facilitate the insertion ofY the follower-plates and springs,I prefer to bevel the ends of the follower-plates, as shown at b b. The pocket is preferably made alike at both ends, as shown in Figs. l to 3, with an opening c at each end i for the passage of the draw-bar shank, so that it is reversible and can be turned in either direction.

In the igures on the second sheet of the drawings I show modifications of my invention, in which the draw-bar shank is attached to the yoke 2 by a rivet-key ll, which may be passed through the transverse slot ordinarily formedin draw-bars for the attachment of the so-called American continuous draftrods and through slots in the arms of the yoke and is upset at the ends, as shown. In these figures also I show a stop-piece l2, made separate from the follower-plates and interposed between the springs, performing the same function as is performed by the projections from the follower-plates shown in Figs. l and 4.

In Figs. l0 to 12, on the third and fourth sheets of the drawings, I show my improvement applied to use with the American continuous system, in which the draw-bars at the opposite ends of the car are connected by transverse keys and longitudinal rods, and to this construction I intend to make Specic claim in addition to my generic claims. In these figures I show the rigging provided with metal draft-arms 13, which may be cast integrally with each other and with the pocket above described and which are abutted against the ends of the draft-timbers 14, of

IOO

which they form a continuation and to which they are secured by boltsl. The draft-arms are also secured to the sills above byV bolts 16 and maybe connected at the top and bottom as well as at the rear by integral webs Or plates, it being necessary only to leave an Opening at the bottom, through which the springs and followers may be removed, and to close said Opening by a removable plate or cap .9. The draw-bar is connected to the arms of the yoke by a key 17, which extends `through the usual slot in the draw-bar,

through slots iu the arms of the yoke, which are preferably doubled, so as to give a better bearing for the key, and through slots in the draft-arms and is adapted to be connected with the draft-rods 19 of the continuous system. In addition to the stop 12 which I show .in these figures I also show as an alternate construction stops 18, either hollow or solid,

which may be set axially in the springs be' between the arms of the yoke and from the tween the follower-plates. The draft-arms shown in these figures are preferably strengtheued by flanges at the sides and constitute a strong and very desirable construction.

The advantages of myinvention will be appreciated by those skilled in the art. springs arranged one above the other, the pocket having horizontal lugs Or abutments for the followers, the free removability of the springs and the followers from lbelow from `pocket, and the construction Of the draftarms shown in Fig. 10, together with the other items mentioned in the claims, constitute, severally and in combination, important parts of my invention.

f I c1aim 1. A draft-rigging having in combination with the draw-bar, a yoke, the arms Of which are connected tO the sides Of the draw-bar,

springs arranged one above the other within the yoke, and followers also arranged between the arms of the yoke, said springs and followers being removable from below, inde@ pendently of the draw-bar; substantially as described.

2. A draft-rigging having a yoke, the arms of which are adapted to be connected to the sides of a draw.- bar, springs arranged one above the other` between the arms of the yoke,

and followers adapted to tit against theends Of both springs, and also contained between the ends Of the yoke, said springs and followers being removable from below independently of the draw-bar; substantially as described.

v3. A draft-rigging having a pocket, lugs, extending horizontally across the pocketat g the upper and lower portions thereof respecl tively, followers within the pocket which bear against the lugs, and a yoke which exi The tends Within the pocket betweenthe lugs and around the rear follower; substantially as described.

- removal'of the spring and followers independently of the draw-bar; substantially as described. l

6. A draft-rigginghavng a yoke open at the bottom and having a spring and followers arranged between the arms of the yoke, a pocket which contains the yoke and is also Open at the bottomto permit removal of the spring and followers, and a detachable closurev for the opening in the pocket; substantially as described.

7. A draft-rigging having, in combination with the draw-bar and spring mechanism, a

.dle ka stop projection which separates the yoke the arms of which are connected to the sides of the draw-bar, a pocket within which the yoke extends, and a 'key which extends horizontally through the draw-bar and yoke, and through slotsin the walls of the pocket; substantially as described. r

8. A draft-rigging having springs set one f above the other, and a follower engaging the ends of both springs and having at the midsprings; substantially as described.

, the jtOp and bottom of the pockets, followersV 9. A draft-rigging having springs set vertically-one above the other, and a single pocket having at oppositev ends horizontal lugs at in the pocket set between the lugs, andadapted to receive a spring between them; a-nd a yoke which extends Within the pocket beg tween the lugs; substantially as described.

10. A draft-riggi ng having springs arranged "vertically, one above the other, followers, a

yoke between thev sides of which the springs land followers are set, said springs and fol- ,lowers being removable vertically from below independently of the draw-bar; substantially as described.

In testimony whereof I have hereu'nto'set lmy hand this 6th day of April, 1900.
